Composition for gravel or granite roofi ng



UNITED STATES PATENT OFFICEO THOMAS VAUGHAN, OF MILLVALE, PENNSYLVANIA.

COMPOSITION FOR GRAVEL OR GRANITE ROOFING, 80C.

EPECIPICATION forming part of Letters Patent No. 310,625, dated January 13,1885.

Application filed November 19, 1883. (No specimens To all whom, it may concern.-

Be it known that I, THOMAS VaUGHAN, a citizen of the United States, residing at Millvale, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Composition of Matter to be Used for the Manufacture of Gravel or Granite Roofing and for other Purposes, of which the following is a specification, combined in the proportions stated, viz:

Five pounds of pitch; one-half pound of rosin; one-halt pint linseed-oil; one ounce beeswax; four drains carbolic acid, liquid or crystallized.

In preparing the above composition for use, the linseedoil, rosin, beeswax, and pitch should be first placed in a suitable vessel and brought to a boiling heat. The carbolic acid should then be added. The solution is then ready for use.-

The solution is to be applied, when hot and in a liquid condition, to any surface, material, or thing it may be desirable to coat with said composition, and particularly the surface of such coarse canvas or thick paper as is generally used for roofing or the covering of framehouses, and which canvas or paper so coated with said composition may, in addition thereto, be dusted over or impregnated with sand or fine gravel, by which the same may be made fireproof and more durable, at the same time improving its appearance.

The advantage of the use of carbolic acid lies in the fact that when a thin coating of the composition is applied to wrappingpaper (and it may be thus advantageously applied) said paper is thereby rendered proof against moths. This is a desirable condition of the paper when used for wrapping woolen goods. The other elements of the composition will render the paper impervious to water. It will thus be seen that the combined effect of all the parts,whena thin coating is applied to the surface of wrapping-paper, is to produce a pa per which is both impervious to water and moth-proof.

What I claim,and desire to secure by Letters Patent, is-

l. The herein-described composition, consisting of linseed-oil, pitch, rosin, beeswax, and carbolic acid, in about the proportions specified.

2. The herein-described composition, consisting of linseed-oil. pitch,rosin, and beeswax, said parts being mixed and boiled, and carbolio acid added to said boiling mass, in about the proportion set forth. I

3. As a new article of mamifacture, paper, felt, canvas, or other fabric coated with a composition of linseed-oil, pitch, rosin, beeswax, and carbolic acid, substantially as set forth.
